Introduction

The -get_byte option prints the values of selected bytes in the grib message. For example if you want to see the 20 and 21 octet (byte in WMO speak) of section 4, you would use -get_byte 4 20 2. The first argument is the section number. The second is the byte (octet) number starting from 1 (consistent with WMO documentation) and the third is the number of octets to display.

Usage

-get_byte SECTION OCTET NUMBER
SECTION = section of the grib message to print
OCTET = starting octet to start printing, OCTET ≥ 1
NUMBER = number of bytes to print

Example

$ wgrib2 f.grb2 -get_byte 0 1 16
1:0:0-1=71,82,73,66,0,0,0,2,0,0,0,0,0,0,18,178
